in vertical internal combustion engines,

1:0 the dismounting ot the piston, connecting rod and crank shaft, is generally attended by considerable ditliculty, and it is necessary that considerable space be available both ,above and at the ends of the. engine. To 15 etl'eet. a simple examination ot the piston,

the conneiding rod, the head of the connectrod or the cylim ler, it, is usually necesv -sary to dismount the cylini ler head and all oi the valves and other distril'mting devices. 20, The mere retutjnstment ot a bearing of the. w crank sha't't oltcn requires the complete dislnonnting of the engine. The protracted and troublesome character ot' these operations is mani test.

rarely requires to be adapted i udismounted and is there'lore readily ..to the vertical type, but the piston and cylinder of an internal combustion engine lworking, for example, with a poor quality cleaned 'lhe. ditliculty llittttY- to been an obstacle in the employment. ot'

t with comparative triapicuev.

,7 teombustion or explosive engines ot the vertieal type where considerable power is requit-ed. i

The object ot the present invention is to obviate these disadvantages by constructing the engine in such a manner that the several 40 parts may be readily dismounted and re assembled.

In the acctnnpanying drawings: Figure 1 is a vertical transverse section of an engine embodying my improvements, with certain parts omitted, and Fig. 2 is a vertical longitudinal section of the engine, also with parts omitted.

The frame ot the engine comprises two separate parts i and J, of which the part or section I. carries the cylinder and the working portions oi the engine white part '3 extends along one side ol' the engine and torms a door for the crank case. The door 2 is fixed to the main frame of the engine and to the base plate in such a manner that it can" be readily detached. but when in position it; terms with the part 1 a structure which is absolutely rigid.

The door or section "2 is provided at the top aml bottom edges with tlanges 2. 2, respectively, which abut amt are attached to the engine frame I. and the base 3 respectively. the connection being made by means ot suitable nnttcd bolts 5. as shown. The door 2 may be divided transversely into a number of sections or panels, it desired, and in order to prevent the door from buckling the latter is strengthened in the direction of its vertical axis. by means ot tlangcs such as shown in Fig l.

in order to strengthen the entire engine t'ramc aml tirmly support, the door or section 2. while still atl'ording easy access to the. crank shalt, bearings. the part 1 is provided with internal cross pieces or webs l which extend across the crank case in the manner shown. lCach cross web 1 rises .l'rom the base portion ot the main tra|ne, at a point alongside the crank shatt bearings, amt it is curved over said bearings, as shown, in order to leave a tree space above the latter, said cross pieces or webs being directed laterally at a distance above the tops of the bearings in order to overhang the latter with sutlieient clearance and to present suitable supports adjacent the door 2 for the attachment and support of the latter. in the embodiment shown. the laterally projecting ends t of the cross webs t are provided with hearing plates or abutments 1" against which abut corresponding brackets or plates it carried by the door it as shown in Fi 1. The brackets 2" at the door are clamped against the lnrackcts t at the main'engine frame by means of bolts '2. and tbs intermediate portion ot the door, which abuts against the laterally directed cross piece of the main tv'ame is thcrctore lirmly but detachabiy supported. ,\s the door p is attached to the main traine not only at the edges but also at the intermediate portion, a very rigid structure is obtained, and yet; the door may be easily removed when required, simply by loosening the tastiening botts.

()wing to the cutout or recessed pbrtion of each cro piccc t, which creates a space between the bearings ot the crank shaft 8 and the door supporting portion of the cross piece, the crank shaft may be readily dismounted in a direction parallel to thatin which it normally lies, and the crankbearings areea sily accessible for this purpose when the door 2 is removed. When the door isunbolted and removed in a lateral direction, the main frame 1 will alonebcar the Weight of the engine parts, and easy and complete access can be had to the interior of the engine for dismounting the pedestal cap pieces, the upper and lower ends of the connecting rods, and for the purpose of re moving the connecting rods, pistons and crank shaft.

In order to facilitate the dismounting and remounting of, the parts it is advisable to fix the pivot 9 to the connecting rod instead of forming it as apart of the piston. Thus it is possible to have a thinned connecting rod .body 3 which will prevent the piston from necting-rod may be effected without dithculty'by loosening the clamp 7 and forcing the pivot 9 to the side.

It will therefore be seen that my invention provides a strong and rigid engine frame having one or more detachable casing sectionswhich, when removed, permit easy access to the interior en me parts and the 'ready dismounting, a justment and remounting of the latter. The removal of the cylinder head and all of the devices usually fixed on the upper partof vertical internal, combustion engines (distributing devices, valves, pipes, regulating devices, accessories,

etc.) is dispensed with. The space required above and at the ends of the engine is reduced to a minimum as a result of the comlete access to theworking parts which may be obtained through the longitudinal pas- 2. In a vertical internal combustion engine, a main frame having an opening extending along one side of the crank case, a door to close said opening, and a cross piece secured to the'main frame and extending transversely within the crank case, said cross piece being detachably secured to the intermediate portion of the door.

3. In a vertical internal combustion engine, a main frame having an opening extending along one side of the crank case, a

door for closing said opening detachably connected at its edges to the adjacent parts of. the engine frame, an inwardly projecting bracket on the middle portion of the door, and means extending across the crank case and presenting a second bracket to which said first named bracket is detachably bolted.

4. In a vertical combustion engine, a main frame having an opening at one side of the crank case, a door to close said opening, a cross web secured to the main frame of the engine within the crank case, crank shaft bearings in the crank case which are overhung by said cross web at such a distance as to permit the removal of the crank shaft in a direction parallel to its normal position,

and means for securing said door detachably to said cross web. a In testimony whereof I have. hereunto set my hand in presence of two subscribing witnesses.
